IPC: G01N29/24
Filed: 1938-07-09
Abstract: 510,484. Syringes. COLE, S. F. July 9, 1938, No. 20374. [Class 81 (ii)] A syringe for medical and like purposes comprises a stop member 21 adjustable with respect to the syringe barrel 1 for limiting the stroke of the plunger 7, the stop member being connected to a sleeve 11a and b which is screw-threaded on the barrel and the edge 15 of which co-operates as an indication with a scale 4 provided on the barrel, the said edge bearing a second scale 14 which co-operates with the longitudinal index line on the barrel, so as to allow the adjusting or reading of fractions on the first scale. The barrel may be of glass having a screw threaded collar 6 cemented to the upper part which engages with the interiorly threaded part 11a of the sleeve. On this is mounted the part 11b which, in addition to the scale has two finger grips 23. At the outer end of the sleeve is mounted the cap 16 having the stop 21 which surrounds the push rod 9 attached to the plunger. When the sleeve is adjusted to the zero graduation the stop, engages the end of the plunger and pushes it to the fully discharged position. In order to prevent the scale being hidden by the fingers when holding the end of the barrel the scale is offset from the end and the plunger correspondingly lengthened. In order to lock the sleeve in a predetermined position the part of 11a over which the part 11b fits is provided with two longitudinal slots 25 the region so treated being flattened, the flattening being progressively increased towards the part 20, thus providing a wedge shaped flexible tongue 24. In the part of 11b which fits over part 11a and which covers the flexible tongue is a slot through which protrudes a member 27 having a wedge-shaped inner surface complementary to the tongue and which when pusb ed towards the nozzle forces the tongue inwards, thus locking the sleeve in position on the barrel by the pressure between their threaded portions. In modifications the barrel and collar 7 may be in one and formed of metal or other less fragile material. The outer end of the plunger may also be provided with an outwardly projecting flange between which and the end of the barrel is accommodated a spring to withdraw the plunger. In operation the sleeve is set and if desired locked at the desired volume and the plunger withdrawn until prevented by the stop. The syringe may then be operated in the normal manner or the plunger may be propelled by rotating the sleeve in the manner of a micrometer.

Patent GB-835750-A (GB)
Title: Manufacture of polychlorobenzenes
IPC: C07C17/00
Filed: 1956-07-04
Abstract: Catalysts for the preparation of polychlorobenzenes by the chlorination of benzene hexachloride (see Group IV (b)) comprise a mixture of gas adsorption carbon and a metal chlorination catalyst prepared for example by treating gas adsorption carbon with an aqueous solution of aluminium chloride, ferric chloride, chromic chloride or an aluminium chloride-cupric chloride mixture and heating.  A mixture of active carbon and active alumina may also be used.ALSO:Polychlorobenzenes are made by reacting hexachlorocyclohexane and chlorine in the gas phase using as catalyst a mixture of a gas-adsorbing substance, for example gas-adsorbing carbon, and a substantially non-volatile metalliferous chlorination catalyst, preferably an oxide of an element, the halides of which act as Friedel-Crafts catalysts, either singly or in admixture with one or more other metal compounds of similar volatility.  The reaction is suitably carried out by causing the reaction mixture to react first in contact with a catalyst of lower activity, for example one of the components of the mixed catalyst such as alumina, and then bringing the partially reacted mixture into contact with the mixed catalyst. The preferred catalysts comprise a mixture of gas-adsorption carbon and alumina or ferric oxide, made, for example, by saturating the carbon with a solution of Al2O3.6H2O and heating to convert the aluminium chloride with aluminium oxide.  Examples describe the conversion of benzene hexachloride to hexachlorobenzene according to the invention using as a catalyst gas adsorption carbon saturated with aqueous solutions of (a) aluminium chloride, (b) ferric chloride; (c) a mixture of aluminium chloride and cupric chloride and (d) chromic chloride, and converted to the oxide by heating, and also using as catalyst a 1 : 1 mixture of alumina and active carbon. Tetrachlorobenzene may also be formed.

Title: A process for resolving an azeotrope consisting of methanol and a tri-borate ester of methanol, or consisting of ethanol and a tri-borate ester of ethanol
Inventor: MAY FRANK HENDERSON
IPC: C07F5/04
Filed: 1957-07-03
Abstract: An azeotrope consisting of methanol and trimethyl borate, or ethanol and triethyl borate, is resolved by feeding boric oxide, metaboric acid or mesoboric acid to a reaction vessel, and feeding said azeotrope to said vessel, and heating, so that a reaction takes place producing a boric acid and additional ester.  The reaction product from said vessel may be distilled to separate the azeotrope and additional ester, the azeotrope and still bottoms from the distillation being recycled to the said vessel. Boric acid is recovered from the vessel as a solid phase and may be reacted with further methanol to form azeotrope.  When the methanol-methyl borate azeotrope is being resolved, additional methanol may be added to the vessel.  The process may be effected on a batchwise or continuous basis.

Title: Production of chlorinated hydrocarbons
IPC: C07C17/158
Filed: 1963-05-28
Abstract: Chlorinated hydrocarbons are prepared by reacting (a) aliphatic C1 to C4 hydrocarbons and/or their incompletely chlorinated derivatives, (b) an oxygen-containing gas, and (c) chlorine and/or hydrogen chloride in a fluidized bed of metal halide oxychlorination catalyst particles, the velocity of the product gas emerging from the fluidized bed being reduced in a vapour zone above the bed, subsequently increasing the velocity above that at which the gases are removed from the bed and imparting a circular motion thereto to thereby deposit entrapped fines in the zone of increased velocity and removing the gas substantially free from fines from said zone whilst maintaining said zone at a temperature above the dew point of the gas.  The increase in gas velocity may be effected by introducing the gas into a restricted orifice or inlet of a dust collector or cyclone and so increasing the velocity by the Venturi effect.  Preferred catalysts are copper chloride-potassium chloride and copper chloride-zinc chloride-calcium chloride catalysts.
